Why doesn't delete set the pointer to NULL?
...
Stroustrup himself answers. An excerpt:
C++ explicitly allows an
implementation of delete to zero out
an lvalue operand, and I had hoped
that implementations would do that,
but that idea doesn't seem to have
become popular with implementers.
But the mai...
Rename a class in Xcode: Refactor… is grayed out (disabled). Why?
...
If you are using Objective-C++ (i.e. mix Objective-C with C++ code) then refactoring is disabled in xcode since it does not support refactoring of C++ code.

What happens to global and static variables in a shared library when it is dynamically linked?
...tions) are never visible from outside a module (dll/so or executable). The C++ standard requires that these have internal linkage, meaning that they are not visible outside the translation unit (which becomes an object file) in which they are defined. So, that settles that issue.

What is the difference between public, protected, package-private and private in Java?
...I control. (While not Java syntax, it is important for this discussion).
C++ defines an additional level called "friend" and the less you know about that the better.
When should you use what? The whole idea is encapsulation to hide information. As much as possible you want to hide the detail of...
Is floating-point math consistent in C#? Can it be?
...g floating point operations. Most information is probably specific to C or C++, however.

A note on fixed point
Binary fixed point numbers can also work well as a substitute for floating point, as is evident from the four basic arithmetic operations:

What is the strict aliasing rule?
...ably has instructions to load buff's contents. Then again, maybe you're in C++ and this is some templated header only implementation that the compiler thinks it can inline. Or maybe it's just something you wrote in your .c file for your own convenience. Anyway undefined behavior might still ensue. E...
“:” (colon) in C struct - what does it mean? [duplicate]

I still don't get it. Does that mean C++ automatically merges your "variables" into size of an int, so that all bits are used? Can you cast bit field structiores to numbers to obtain the typical "int with flags".
